When you enable two-factor authentication on your accounts, jun88 đăng nhập you’re provided with emergency access codes that serve as a failsafe if you lose your phone. These codes are your final access key—so storing them safely is essential. Do not keep them in the your password manager or in an plain text file on your tablet. If a unauthorized person gains access to your digital account, they could extract your backup codes and take full control.

Instead, print the codes on paper and keep them in a secure physical location like a locked drawer. Make sure the paper is isolated from extreme heat and other damage hazards. If you’re worried about destruction, consider making two copies and storing one in a different secure location such as with a close friend or in a bank vault.

If you prefer digital storage, select a verified credential keeper that is encrypted end-to-end and locked behind a complex passphrase. Avoid using cloud note apps like Apple Notes unless they are encrypted with a master key. Never text recovery codes to yourself or save them to Google Drive that can be accessed by others.

Validate your codes every few months to ensure you can still access your accounts using the codes. If you update your passwords, refresh your backup set. Remember, recovery codes are irreplaceable once lost—so handle them like a passport. Their security is your security.
